COD-571 chemical oxygen demand tester abandons the traditional complicated and bulky spectroscopic system and adopts a new type of LED as the light source, which greatly reduces the volume and weight of the measuring equipment. Equipped with a dedicated digestion device, the sealed reflux digestion method can be used to heat and reflux 21 samples at the same time. It is convenient to operate, fast in digestion, and can save a lot of water, electricity and reagents, and reduce secondary pollution. COD-571 is suitable for environmental protection industry and is convenient for COD determination of large quantities of samples.
